I think I would consider lemon tart to be the most dangerous dessert. Not dangerous in the way of Japanese fugu or anything, I’m not claiming that it will kill you if incorrectly prepared, but dangerous in that capable-of-completely-abolishing-all-willpower sort of way. There’s something about the irresistible mix of buttery pastry, silky custard, and the snap of lemon that seems to prevent you reaching that overload threshold you get with other desserts. Because it has a welcome acidity from lemons, you can just keep on going without feeling yourself slip into a sugar coma. Until you do, of course, slip into a sugar coma, one that has crept up on you like some kind of saccharine ninja and left you defenceless.
